t1465: Fix PLUGIN_NAMESPACES unbound variable in deploy-agents-on-merge.sh

[marcusquinn]

Summary

• make plugin namespace iteration nounset-safe for Bash 3 empty arrays
• preserve existing deploy behavior for configured namespaces across full and selective sync paths
• validate dry-run deploy flows with and without namespace config

Closes #4478

Summary by CodeRabbit

• Chores
  • Improved deployment script reliability by making plugin-namespace handling robust during dry-run deployments—preserves existing behavior when plugins are present and safely handles cases with no plugins configured, reducing potential failures and confusion.

Walkthrough

Dry-run path in .agents/scripts/deploy-agents-on-merge.sh now iterates over PLUGIN_NAMESPACES with safe expansion instead of referencing PLUGIN_NAMESPACES[@] conditionally, preventing unbound-variable errors in strict mode while preserving behavior for populated arrays.

Changes

Cohort / File(s)	Summary
Deployment script ​.agents/scripts/deploy-agents-on-merge.sh	Replaced conditional append that referenced PLUGIN_NAMESPACES[@] with a safe iteration/expansion to avoid PLUGIN_NAMESPACES[@]: unbound variable under strict mode; dry-run behavior preserved for non-empty arrays.

Poem

🔧 An array once triggered a warning's chime,
Now looped with care, no panic this time.
Strict mode sleeps sound,
Dry-runs safe and sound,
Deploy sings along in tidy rhyme 🎉
